Get semantic model from a classifier VSIX

Question

As R# is not supporting the Roslyn Early Preview C# 6.0 features, the code looks very dull...

I would like to colorize the code using a classifier VSIX. Is it possible to get the semantic model from the Roslyn Language Service for the current document?

Answer 1

You need to add a reference to Microsoft.CodeAnalysis.EditorFeatures.Text.dll, then use the following code.

var doc = point.Snapshot.GetOpenDocumentInCurrentContextWithChanges();
var model = await doc.GetSemanticModelAsync();

This requires the Microsoft.CodeAnalysis.EditorFeatures.Text NuGet package (.NET 4.6 required)
